Problems solved by technology
[0002] CNC milling machines and ordinary milling machines need to clamp the workpiece when milling or welding the workpiece. The current clamping method is to rely on the clamping plate clamping or the centering clamping of the three-jaw chuck. This clamping method takes a long time to clamp. Affect production efficiency, especially in the process of repeated trial clamping in mass production, not only affect production and processing efficiency, but also affect the centering accuracy of the workpiece, and reduce the machining accuracy of the workpiece

The invention discloses a quick pneumatic cam clamping device comprising a base, a rotary cylinder arranged on the base, a double-sided cam mounted on the cylinder and push rods. The push rods are located on two sides of the double-sided cam and movably connected with the base, one end of each push rod is in contact connection with the double-sided cam, pressing plates are arranged on two sides of the base and movably connected with supports which are fixedly connected on the base, one end of each pressing plate is a clamping part, the other end of each pressing plate is movably connected with the other end of the corresponding push rod, and a return spring is arranged on each pressing plate and between one side close to the clamping part and the position corresponding to the base. The clamping apparatus can improve production efficiency significantly, is applicable to batch production and has the advantages of high clamping force, rapid action, convenience in operation and the like.
Description
technical field [0001] The invention relates to a pneumatic cam quick clamper, which is mainly used in the working occasions where the workpiece needs to be quickly clamped when the workpiece is milled by a numerical control milling machine and an ordinary milling machine and the workpiece is welded. Background technique [0002] CNC milling machines and ordinary milling machines need to clamp the workpiece when milling or welding the workpiece. The current clamping method is to rely on the clamping plate clamping or the centering clamping of the three-jaw chuck. This clamping method takes a long time to clamp. It affects production efficiency, especially in the process of repeated trial and clamping in mass production, not only affects production and processing efficiency, but also affects the centering accuracy of the workpiece, and reduces the machining accuracy of the workpiece. Therefore, it is a technical problem that those skilled in the art urgently need to solve to ...
